Hello RDF!

Recently after purchasing an Infiniti I found myself experiencing the pleasures of the open road a little too often. Worried I would find myself facing a future unwanted LEO interaction, so I dug up my trusty old Escort 7500. I had abandoned the use of my Escort 7500 and RDs in my previous car years ago due to changes in my life. Unfortunately I didn't even get to drive around using it due to it constantly going off with Laser and K-band alerts while just being parked. At first I thought the RD was malfunctioning after sitting for so many years in the glovebox. When unmounting the unit and changing the orientation, the alerts stopped. After playing around a bit I decided it was due to interference from the car itself. This was verified by installing the 7500 back into the VW and not having an issue.

I knew from friends who were still running RDs and V1s that there are so many things now that will set RDs off (V1s especially!). I figured there were more advanced RDs now so I should look a purchasing a new Escort. After being shocked by the pricing of the Escort Max/2/360 pricing I decided to do a bit of research. A few months after finding @Vortex on youtube then following RDF, I took an informed plunge.

Uniden LRD950 for Radar and now an ALP Quad package for Laser Interference Defense.​


After receiving my ALP Quad today I proceeded to set it up on the bench to test functionality before installing. I found the ALP rebooting after getting hit with a ProLaser 2/3/4 while in Parking mode after a JTK. WTF!

Has anyone else seen this or is able to replicate the issue?


Test Setup:

  • ALP (Hw 2)
FW: 5.2.1
PDC FW: 6.5
Region: NA
Defense FW Installed, HiFi Pack installed, English Female Voice Pack,​
  • (1) Sensor connected to F1
  • HiFi Control Pad (connected to ALP Connect)
  • ALP Connect Bluetooth Module
  • ALPConnect 1.8A for Android (Samsung Note4)
  • LASER Interceptor LIDAR Emulator Tool

Test 1 (Bluetooth Procedure):
  1. Power on ALP and wait for Defense mode to activate
  2. Open ALPConnect, verify connectivity to BT module.
  3. Wait for Defense mode to activate on App
  4. Shoot any Laser gun for any amount of time to verify detection/defense.
  5. Wait for Auto JTK or Manual JTK
  6. Shoot ProLaser 2/3/4/ Laser Atlanta for around .25 to .5 sec
ALP will reboot, BT drops connection, ALP ready, BT reconnected, Defense mode no warmup.

Test 2 (HiFI Procedure)


  1. [*=1]Power on ALP and wait for Defense mode to activate
    [*=1]Open ALPConnect, verify ALP is disconnected via BT module.
    [*=1]Wait for Defense mode to activate on HiFi / Keypad
    [*=1]Shoot ProLaser 2/3/4/ Laser Atlanta for any amount of time after detection/defense
    [*=1]Wait for Auto JTK or Manual JTK
    [*=1]Shoot ProLaser 2/3/4/ Laser Atlanta for as long as you want
ALP will function properly without issue.
It seems like it might be a firmware issue in the BT module or between the BT module and the ALP. I did go ahead and update the firmware using the App as well without a change in the results.

Thanks for all of the support to Vortex, BRD and RDF Forum Members like you! I appreciate all of the hard work and dedication.

This is completely normal and the way the system was designed. You get hit and the LID timer kicks in and it will kill automatically after your time limit and then reset and come back online in 60 seconds.

I understand the unit will normally be in "Parking Mode" after JTK, but that is not what it is doing as stated in Test 1 compared to Test 2. The unit is rebooting not timing until defense reset. The ALP led goes solid green then a relay clicks power cuts, then firmware startup over HiFi ignoring the config (warmup on boot). This only happens when shot with a ProLaser 2/3 or 4 in Parking mode when Bluetooth is connected.


If you repeat Test 1 using any other gun (Non ProLaser) in Steps 4 or 6 while the Bluetooth is connected, the unit functions as expected... 60 sec LID timer then Defense mode active.

Also if you do not connect your phone via Bluetooth (As test 2 shows) the ALP functions properly... No rebooting! No matter which gun is used and when.

Seems like an buffer overflow in firmware.

Sorry, Only skimmed the original post because I was at a red light and only had a few seconds to respond before it changed. Please do me a favor and pull a statistics report and that will write a config.alp and stats.alp file to the thumb-drive and email me those 2 files so I can duplicate all your settings and see if I can duplicate it. Also if you can make a quick video of what is happening for you it would be helpful.

Just to add another data point... I don't have the BT, just the HiFi, but I did notice one time if I have the ALP in parking mode (either via warm-up, or the quick press of the menu button, or a PDC-only profile) AND I have the LED set to flashing, the LED goes steady green when I shoot my PL3 at the ALP.

I haven't tried other pulse rates to see if it happens with those (I have to use a tester for that) but the fact that the LED stops flashing while receiving pulses from a PL3 while in parking mode might have some effect on causing the BT module to reboot the ALP. Maybe I'll try tomorrow...

I was playing around...
I don't have this problem, but I have another one ...


Scenario #1

LID time 4 sec... shoot... press screen before 4 sec... goes green PDC for 60sec... doesn't disconnect

Scenario #2

LID unlimited... Shoot... press screen... it goes to DLI for few sec and back to LID... Doesn't go to 60 sec warm up PDC...
I know guys with HIFI are using unlimited, and it goes to warm up if they click on it... but BT doesn't... at least in my case...

In Unlimited there is no 60 second warmup. This is the same regardless of the controller.

Good to know. Thank you for clarifying that.
For how long then it give them option to read your speed after pressing buttons (no BT) or screen (BT)?
Some guys use unlimited all the time...

When they stop shooting in Unlimited it goes back to defense mode after like a 2 second pause.

Is there an ETA on the firmware update? I have been holding off the install primarly for this reason.

Why would you hold off... This small issue has nothing to do with protecting you. The reboot occurs during the recycle period and instead of going offline for the 60 seconds it actually comes back online quicker with the reboot.

Because it is not good if the unit keeps immediately rearming to Laser Defense.

If I have to constantly keep hitting the pad of phone/tablet (another thread needed) at the right time to JTK my focus is not where it should be. My focus should always be on controlling the vehicle and preventing an accident. If I did not kill the jammers/defense this would create the possibility of an unwanted suspicious LEO interaction.


I feel this firmware issue, if not vigilantly monitored and controlled by driver would violate one of the basic rules: Never JTG.

It only does it after you kill a real threat and you have it set to go offline for 60 seconds. Instead of 60 seconds it will come back online in around 10 seconds. You would have passed the threat and already gave them a reading immediately when you kill or the LID timer kicks in. This is a non issue in normal use and only happens on a few specific guns.
